  1. Hi Friends

     

    I wanted to play a little on my vectrex but it didn't work normally

    When the vectrex is 'cold' I switch on the vectrex, everything seems to be good but few seconds later, it's like a characters desintegration on the screen. The 3d part seems to be good.

    Do you encouter this problem ? where could it come from ?

     

    thanks friends

    My Vectrex display problem


  2. Hi friends,

     

    I write this little message for an advice. I'm still working on my first game for colecovision and learn every day I open my computer to code on Wii?.

     

    From rle I had to move to pletter (I have some things to had but Wii? was about 31KB)
    (all my graphs are 'pletterized'. From about 31KB, I've got now about 27KB)


    What I've done :

    I've integrated pletter_dan.s in my sourcecode and I've replaced the following procedures

     

    load_patternrle(Wii_LOGO_PATTERNRLE);
    duplicate_pattern();
    rle2vram(Wii_LOGO_COLORRLE,coltab);
    rle2vram(Wii_LOGO_COLORRLE,coltab+2048);
    rle2vram(Wii_LOGO_COLORRLE,coltab+4096);
    rle2vram(Wii_LOGO,chrtab);
    rle2vram(Wii_OEIL_SPATTERNRLE,sprtab);

    Pletter_Menu();
    duplicate_patten();

     

    with


    static void Pletter_MENU(void)
    {
    __asm
        ld hl,#_Wii_LOGO_PATTERNRLE
        ld de,#0x0000
        call _Pletter
        
        ld hl,#_Wii_LOGO_COLORRLE
        ld de,#0x2000
        call _Pletter

        ld hl,#_Wii_LOGO_COLORRLE
        ld de,#0x2000+2048
        call _Pletter

        ld hl,#_Wii_LOGO_COLORRLE
        ld de,#0x2000+4096
        call _Pletter

        ld hl,#_Wii_LOGO
        ld de,#0x01800
        call _Pletter
        
        ld hl,#_Wii_OEIL_SPATTERNRLE
        ld de,#0x3800
        call _Pletter    
    __endasm;
    }


    It works but is this ok for you or not ? I just want to make less mistakes :) I'm still learning and this forum is the best place to have some answers, solutions, help, ...

     

    Thanks in advance for your help

  3. For the last point, without triggering the Early Clock, sprites disappear suddenly when reaching left border. With EC, sprite desappear pixel by pixel when reaching the left border (like it does when it reaches right, up, or down border).

     

    Maybe for a next project, I have to study sprite flikering

     

    Thx a lot ;)


  4. Don't worry, your solution is welcome ( and any other) ;)

     

    by the way, in my WIP17 video, at 2:12 / 13 - a white square (16x16) appear at the top right of the screen.

    Is there a kind of sprite initialisation problem ? Maybe I am doing something wrong ... (it's possible ;) )

     

    See you and thanks a lot

     

    Eric
